ABSTRACT
The overall objective of this project is to apply mobile air sampling strategies and novel health assessment and
communication tools to rapidly characterize sustained health risks from hazardous volatile organic compound
(VOC) exposure during the remediation and recovery phases of the East Palestine, Ohio environmental disaster.
This research builds from ongoing mobile air sampling in East Palestine conducted as part of the Texas A&M
University Superfund Research Center (TAMU SRC) showing elevated VOC levels, particularly acrolein, that
vary spatially across the East Palestine township. The overall goal of the TAMU SRC is to characterize and
manage the human health risks associated with exposure to environmental emergency-mobilized hazardous
substances. The situation in East Palestine exemplifies the critical data gaps in both exposure and health risks.
Current ambient air monitoring approaches lack fine spatial resolution. Additionally, standard methods like those
used at EPA stationary monitors use “targeted” approaches, missing potential novel chemical exposures.
Importantly, there is also a lack of critical health information despite the documented environmental concerns
following the East Palestine train derailment, chemical spill, and controlled burn. Generally, there is very limited
data on the health impacts associated with these occurrences. Thus, the central hypothesis of this project is that
VOCs may vary spatially based on phases of the recovery, and mobile air sampling data in combination with
resident self-reported symptoms will inform localized hotspots of VOC mixtures. To determine the distribution of
VOCs over time as cleanup efforts continue, aim 1 will sustain mobile air monitoring by taking measurements
that are highly spatially and temporally resolved at 9-, 12-, and 15-months post-disaster. Aim 2 will focus on
interpreting VOC data, contextualizing risk, and collecting health data using validated surveys identifying
chemical and non-chemical stressors, addressing physical and mental health, and unique chemical sensitivities.
Also, the application of an innovative AI text messaging application for residents to freely report health and
environmental concerns through a chat bot will provide a means for continued health surveillance. Overall, the
novel tools and findings from this project will directly inform hyperlocal air quality and residential health concerns
following an environmental disaster that can serve as a template for responding to air pollution in disasters.
